"PPP Tunneling Using Layer Two Tunneling Protocol Version 3 (L2TPv3)", Carlos Pignataro, 10-Jul-08. ( bytes)

This document describes the use of "version 3" of Layer Two Tunneling Protocol (L2TPv3) to tunnel Point-to-Point Protocol (PPP) packets. This document defines the control protocol and encapsulation specifics for tunneling PPP over L2TPv3, and is a companion document to the L2TPv3 base specification.

"Layer Two Tunneling Protocol - Setup of TDM Pseudowires", Sharon Galtzur, Alexander Vainshtein, 29-Oct-08. ( bytes)

This document defines extensions to the Layer Two Tunneling Protocol (L2TP) for support of structure-agnostic and structure-aware TDM pseudowires.

"L2TPv3 Extended Circuit Status Values", Neil McGill, Carlos Pignataro, 19-Nov-08. ( bytes)

This document defines additional Layer 2 Tunneling Protocol Version 3 (L2TPv3) bit values to be used within the "Circuit Status" Attribute Value Pair (AVP) to communicate more granular error states for Access Circuits and Pseudowires. It also deprecates the use of the New bit in the "Circuit Status" AVP, updating RFC3931.
